Just bought my first Porsche! Car ran fine when I took it for a test drive.(was already warmerd up). Tried driving nexy day (cold start) would not rev above 2000 rpm till warmed up. Drove for a few days and now will not rev above 2000 rpm cold or warmed up without breaking up. Car runs fine up to 2000 rpm. Checked fuel pressure,replaced spark plugs,switched coils. Tested air flow sensor with cheap ohm,volt meter did not seem to test as good as it should. Took plastic cover off air flow sensor and repostioned tabs. Did not seem to help. I ordered a used air flow sensor. Have not recieved it yet to try. Am I on the right track? Is there anything else I should test or try? Geting frustrated! I want to drive my Porsche!
